Ali Larijani has called on Muslim-majority countries to unite with Iran against the United States and Israel, criticizing Islamic governments for what he described as insufficient support during the ongoing conflict.

In a statement published Monday on his account on the social platform X, Larijani accused United States and Israel of launching what he called a “deceptive American-Zionist aggression” against Iran while diplomatic negotiations were still underway.

Larijani said the attacks led to the deaths of senior leaders of the Islamic Revolution as well as civilians and military commanders. Despite the losses, he claimed that the Iranian public had mounted what he described as “solid national and Islamic resistance.”

“Despite the aggression, the Iranian people, through their strong will, were able to suppress the aggressor enemy to the point that today it is unable to find a way out of this strategic impasse,” Larijani wrote.

The senior Iranian official also expressed frustration over what he described as limited support from other Muslim-majority states. According to Larijani, most Islamic governments have offered little more than political statements rather than concrete backing for Tehran.

Citing a saying attributed to the Prophet Muhammad, he questioned the stance of governments that had not supported Iran during the conflict.

“He who hears a man calling ‘O Muslims’ and does not answer him is not a Muslim,” Larijani wrote, urging Muslim countries to reconsider their positions.

Larijani also criticized regional governments that host American military bases, arguing that Iranian strikes on such installations were acts of self-defense. Some countries, he said, had accused Tehran of hostility after it targeted U.S. bases and American or Israeli interests.

“Is Iran expected to stand idly by while American bases in your countries are used to attack it?” he asked, describing such criticisms as “flimsy excuses.”

Framing the confrontation as a broader ideological and geopolitical struggle, Larijani said the conflict pits the United States and Israel against “Muslim Iran and the forces of resistance.” He called on Islamic governments to determine which side they would support.

The statement comes as tensions across the Middle East continue to rise following extensive U.S. and Israeli strikes on Iranian military facilities and Tehran’s retaliatory attacks on targets linked to Washington and its allies across the region.

Larijani concluded by urging greater unity among Muslim countries, arguing that stronger cooperation within the Islamic world could ensure long-term security, development, and independence from foreign influence.

“The unity of the Islamic Ummah, if achieved with full strength, is capable of ensuring security, progress, and independence for all its countries,” he said.
